Benefits of technology

This patent proposes an improved axle support for multi-track vehicles that reduces the risk of injury to occupants in the event of a collision. The support design prevents the wheel from rotating inward during a collision, reducing the amount of damage to the vehicle's interior. Additionally, the design includes a bearing connection area that is positioned laterally, allowing for deformation in the side member without compromising its strength. The bearing connection area is also angled with respect to the center longitudinal axis of the support, further enhancing its stability. The support profile also includes a wall opening that reduces stiffness and allows for easier displacement of the bearing connection area. Overall, this design improves the safety and performance of multi-track vehicles.

Problems solved by technology

However, because it is essentially undesirable for components to detach from one another in the event of a collision and correspondingly for the structure of the motor vehicle to weaken, on the one hand, and to have free ends present, on the other hand, in this case, a free end of the additional control arm, whereby the risk of injury is increased, a special embodiment of the bearing attachment area shall be provided in which the bearing point is provided to articulate the control arm.

Embodiment Construction

[0032]FIG. 1 shows a schematic representation of an area of a motor vehicle 1, namely an axle support 2, on which a wheel 3 of the motor vehicle 1 is suspended. Coming from the axle support 2, a first side member 4 is shown here. Next to the first side member 4, the axle support 2 has an additional, second side member 5, which is not shown here, however. The two side members, 4 and 5, are connected to one another via a cross member 6, which is also not shown. The side member 4 has a bearing point 7, to which a control arm 8 is articulated, particularly so that it is able to swivel. The control arm 8 is used to connect a wheel carrier, which is not discernible here, in which the wheel 3 of the motor vehicle 1 is mounted so as to rotate. Next to the control arm 8, an additional control arm 9 is provided, which is used to also connect the wheel carrier to the axle support 2, particularly the side member 4. For example, control arm 9 engages further toward the front on the side member 4...

Abstract

The invention relates to an axle support for a multi-track motor vehicle, having a first side member, a second side member, and at least one cross member connecting the first side member and the second side member to one another, wherein at least one control arm is articulated at bearing points of the first side member and of the second side member to connect a wheel carrier for a wheel of the motor vehicle. In doing so, a provision is that each of the bearing points is arranged in a bearing connection area of the corresponding side member, in which the side member has less stiffness perpendicular to its longitudinal extension than away from the bearing connection area.

Description

FIELD[0001]The invention relates to an axle support for a multi-track motor vehicle having a first side member, a second side member, and at least one cross member connecting the first side member and the second side member to one another, in which at least one control arm is articulated at the bearing points of the first side member and the second side member to connect a wheel carrier for a wheel of the motor vehicle.BACKGROUND[0002]The axle support is used to connect the wheel carrier to the motor vehicle, particularly to a body of the motor vehicle. The body is preferably designed as a self-supporting body. The axle support may also be characterized as a subframe or support frame. It is rigidly connected, to the body, for example, bolted to it, for example. In this case, it is characterized as an integral subframe. Alternatively, it may be connected to the body by means of a damper, for example, by way of vibration-damping connecting elements.[0003]The axle support is intended f...
